Effects of Ganoderma lucidum polysaccharide on learning and memory impairment and intestinal flora in mice with D-galactose-induced aging.
Article in Die Naturwissenschaften, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Learning and memory impairment is one of the main manifestations of cognitive impairment. Gut flora can affect cognitive function and behavior through the gut-brain axis. Ganoderma lucidum polysaccharide (GLP) is one of the main effective components of G. lucidum, with antioxidant and anti-aging effects. In this study, the learning and memory impairment model of aging mice was established by injecting D-galactose (D-gal). The learning and memory ability of mice was tested by a water maze experiment. Also, the biochemical indexes of mouse serum and brain tissue were determined. In addition, 16S rRNA sequencing was performed on mouse feces. The results showed that GLP significantly shortened the latency of mice to find a safe platform. Also, they enhanced superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities, increased glutamate (Glu) and acetylcholine (ACh) contents, and decreased malondialdehyde (MDA) and gamma-aminobutyric acid (GABA) contents in mice to improve antioxidant capacity, remove free radicals, and reduce lipid peroxidation and oxidative stress, thereby improving learning and memory disorders in mice. The analysis of the microflora after the intervention of GLP to improve learning and memory disorders in mice revealed changes in Lactobacillus abundance. In conclusion, D-gal causes learning memory impairment and reduced intestinal microbial diversity in aging mice, whereas GLP may ameliorate learning memory impairment by altering the distribution of Lactobacillus in the intestinal tract of mice and regulating the biosynthesis of peptidoglycan and secondary bile acids.
